The objective of the study was to determine the effect of various layer compositions on the properties of 3-layer vertically glued laminated bamboo beam (LBB). Bamboo strips for LBB fabrication were prepared from mature culms (± 4 years old) of andong bamboo (Gigantochloa pseudoarundinacea (Steud.) Widjaja) collected from private gardens in West Java. The strips were pre-treated by soaking them in 7% boron solution for four hours. Three-layer LBBs were manufactured with six different layer compositions, including bamboo combination with wood planks of manii (Maesopsis eminii Engl.) or sengon (Falcataria moluccana (Miq.) Barneby & J.W. Grimes) as the core layer. The LBB was manufactured using Water Based Polymer-Isocyanate (WBPI) adhesive. The glue spread and cold pressing time applied were 250 g/m2 and one hour, respectively. Results showed that the average density, moisture content, thickness swelling, and width expansion of LBB were 0.65 g/cm3; 11.1%; 2.09%; and 1.99%, respectively. No delamination occurred in all samples using WBPI adhesive, which indicates high bonding quality. The average bonding strength and percentage bamboo failure (dry test) of LBB were 61.6 kg/cm2 and 90%, respectively. The physical and mechanical properties of LBB were significantly affected by the layer composition. The presence of wood laminates as the core layer of LBB and the cross wide orientation of the core layer decreased mechanical properties of LBB. On the contrary, the presence of cross-layer in LBB structure increased dimensional stability of the produced LBB.Three-layer thick laminated bamboo beam made of vertically glued andong bamboo strips with various constituted layer composition and all constitued layers laminated together in parallel grain direction had strength values comparable to those of class II of solid wood strength, eventhough the core layer was made of sengon or manii planks.

Penelitian ini bertujuan untuk mengetahui pengaruh komposisi arah lapisan terhadap sifat papan bambu komposit (PBK). Jenis bambu yang digunakan adalah bambu andong (Gigantochloa pseudoarundinacea) berumur sekitar 4 tahun yang diperoleh dari tanaman rakyat di Jawa Barat. Bilah bambu andong yang digunakan untuk membuat PBK diberi perlakuan pendahuluan dengan jalan direndam dalam larutan boron 7% selama 2 jam. Produk PBK 5 lapis dibuat dengan 4 macam variasi komposisi arah lapisan. Bambu lamina dibuat dengan menggunakan perekat isosianat water based polymer-isocyanate (WBPI) dengan berat labur perekat 250 g/m2 permukaan, dikempa dingin dengan lama pengempaan 45 menit. Hasil penelitian menunjukkan bahwa rata-rata kerapatan, kadar air, pengembangan tebal, dan pengembangan lebar PBK berturut-turut adalah 0,79g/cm3, 12,60%, 2,38%, dan 1,13%. Kualitas perekatan PBK yang dibuat dengan perekat isosianat (WBPI) cukup baik yang ditunjukkan oleh tidak terjadinya delaminasi pada semua contoh uji untuk pengujian delaminasi. Keteguhan rekat rata-rata (uji kering) PBK yang dibuat dari bambu andong dengan perekat isosianat adalah 70,4 kg/cm2. Sifat fisis dan mekanis PBK sangat dipengaruhi oleh komposisi arah lapisan penyusun PBK. Sifat mekanis PBK menurun dengan meningkatnya jumlah lapisan silang dalam komposisi lapisan penyusun PBK. Sebaliknya keberadaan lapisan silang dalam komposisi lapisan penyusun PBK meningkatkan kestabilan dimensi PBK yang dihasilkan.

Publisher : Pusat Penelitian dan Pengembangan Hasil Hutan

experimental laminated veneer ( 5 - ply ) were made from 12 wood species veneers glued with urea formaldehyde. Thickness of veneer was 1.5 mm and the range of veneer density was 0.38 - 0.83 g/cm3. Veneers were divided into 3 groups based on their densily i.e. low, medium and high. The laminated veneer properties were tested in accordance with the plywood standards ( JAS and ASTM) the properties tested were density,moisture content, bending strength, tensile strength, compression strength , and moisture resistant. Bonding strengththe results showed that all kinds of wood species combination could be made for laminated veneer glued with urea formaldehyde without any difficullty. The density of laminated veneer was higher than an average veneer density of single. wood species or an average veneer density of mixed wood species. The mechanical properties of laminated veneer increased as the densily of laminated veneer increased and the relationship could be expressed by linear regression equations. As a result, some laminated veneer properties could be estimated from its density without considering its wood species.

Formerly perupuk wood was not recognized as good raw material by wood working manufacturers. Because of the increasing scarcity of ramin wood, the perupuk wood had gained the benefit of the situation as indicated by increasing demand and price of perupuk wood.The technical and economic studies on perupuk wood (Lophopetalum. spp) utilization wascarried out at one wood working mill in Gresik, East Java in 1994. The objectives of the study were to identify kind of products resulted from perupuk utilization, recovery level of each product, productivity and efficiency ofperupuk wood working machineries, and its value added.The study showed that kind of products resulted from perupuk utilization were moulding,smooth-four-side (S4S), finger jointed stick, solid jointed board and finger jointed board. The average recovery of perupuk utilization was 55% and the highest recovery (65.60%) was obtained by smooth-four-side product. The double planer machine had the highest productivity because all products used the machine to get the standard dimensions. The efficiency of some perupuk wood working machineries still low. The value added of perupuk wood working products were 90%, 55%, 52%, 37% and 24% for smooth-four-side, finger jointed board, moulding, solid jointed board and fingerjointed stick respectively.Key words : perupuk, wood working, recovery and value added.
